The problem I have with books of this type, which I think of as attempts to popularize cosmology, is that I'm inevitably confronted with math that is way over my head, when what I'm really interested in is the idea that the author is trying to demonstrate and support with the math: so instead of marveling at the author's genius, I find myself drowning in math that makes my eyes glaze over. Admittedly, this book is also for people that will have no problem with the math, and to them it will mean something, and certainly the math is important. Nonetheless, I was hoping for something a bit more like 'Cosmos', and something a lot less like my first or second year university calculus/algebra/geometry text book.

Nonetheless, the idea of cyclical universes coming and going and coming and going... is an interesting one. The older cosmology gets, the more mystical and weird it gets.
